We’ll try to make our gallery fully compatible with this builder. It’s a new builder and we can’t find original builder sources here in official wordpress extensions directory.
We’ll do our best to make this modifications in our gallery as fast as possible.
I really appreciate that!
You can debug I think with Try Oxygen:–

We have tested everything more close with this builder and actually on test location we have configured gallery without any code fixes, just with compatibility mode in gallery settings.
Here’s test location with robo gallery configured on page with oxygen builder:

Try to switch to forced mode in gallery compatibility settings. Screenshot of the robo gallery compatibility settings: http://prntscr.com/so0ejb
